Abstract

Se proporcionan fibras bicomponentes con curvatura mejorada. Las fibras bicomponentes comprenden una primera región de polímero o primera región y una segunda región de polímero o segunda región. La primera región de acuerdo con las formas de realización de la presente divulgación comprende un interpolímero de etileno / a-olefina y tiene una fracción de detector acumulativo de dispersión de luz (CDFLS) mayor de 0,1200, en donde el CDFLS se calcula midiendo la fracción de área de un cromatograma detector de dispersión de luz láser de ángulo bajo (LALLS) mayor o igual a 1.000.000 g/mol de peso molecular mediante el uso de cromatografía de permeación en gel (GPC). La segunda región comprende un poliéster. Las fibras bicomponentes se pueden utilizar para formar materiales no tejidos.Bicomponent fibers with improved bend are provided. Bicomponent fibers comprise a first polymer region or first region and a second polymer region or second region. The first region according to embodiments of the present disclosure comprises an ethylene/α-olefin interpolymer and has a Cumulative Light Scattering Detector Fraction (CDFLS) greater than 0.1200, where the CDFLS is calculated by measuring the area fraction of a low-angle laser light scattering (LALLS) detector chromatogram greater than or equal to 1,000,000 g/mol molecular weight using gel permeation chromatography (GPC). The second region comprises a polyester. Bicomponent fibers can be used to form nonwoven materials.
